A recently released Sandia National Laboratories report, “Suggested Guidelines for Assessment of DG Unintentional Islanding Risk,” outlines a procedure to help utility distribution engineers determine the risk of unintentional islanding in distributed energy generation installations. By providing a quick and reliable way to identify situations in which such risk is negligible, Sandia’s approach can help [...]
Sandia Truman Fellow Anne Ruffing (8622) has engineered two strains of cyanobacteria to produce free fatty acids (FFAs), a precursor to liquid fuels, but she also found that the process cuts the bacteria’s production potential. She published her work on one strain, “Physiological effects of free fatty acid production in genetically engineered Synechococcus elongatus PCC [...]
Homogenous charge compression ignition (HCCI) engines use fuel mixed with a substantial amount of excess air or recirculated exhaust gas that is compressed in the combustion chamber until it autoignites. The resulting combustion is a flameless and low-temperature burn that consumes less fuel than traditional spark-ignition internal combustion engines, and therefore, produces less carbon dioxide. [...]
Craig Taatjes and David Osborn (both in 8353), along with collaborators at the universities of Manchester and Bristol, were given this LBNL Advanced Light Source (ALS) award for their work in making the first direct measurements of the reactions of Criegee intermediates and showing that their impact on tropospheric chemistry and climate may be substantially [...]
